Description
Technical field
The utility model belong to absorption column of gas technical field more particularly to a kind of efficient gas absorption tower.
Background technique
In the industrial production, it will usually generate industrial waste gas, having containing the air quality that has an impact in the exhaust gas often generated
Evil substance will be greatly reduced air quality and influence human health if directly discharged the exhaust in atmosphere.So in industry
It in production, first has to carry out absorption processing to exhaust gas before discharging the exhaust in atmosphere, by the harmful substance in exhaust gas and clearly
Clean air is separated, and then clean air is discharged again.
In order to realize the harmful substance absorption and separation in exhaust gas, usually exhaust gas is carried out using absorption tower in industrial production
Absorption processing, absorption tower is the contact using gas with liquid, and the harmful substance in gas is transmitted in liquid, nuisance is made
Matter is chemically reacted with liquid, to achieve the purpose that absorption and separation harmful substance.
Currently used absorption tower is packed tower, increases the contact area of gas and liquid using the filler in absorption tower,
When gas passes through filler, the harmful substance in liquid and gas reacts the mesh for reaching absorption and separation harmful substance
's.But occur the problem that by the way of packed tower on the one hand because the volume on absorption tower is bigger, and the cost of filler
It is relatively high, cost can be increased using filler, and difficulty of processing is big；Another aspect filler is arranged in inside absorption tower, meeting
It is contacted with absorption tower, when filler is handled exhaust gas by Hquid, the liquid that filler is absorbed also can be to suction
It receives tower and generates corrosion；Finally, when liquid load is smaller, filler surface cannot be effectively soaked using packed tower, thus to useless
The efficiency of aspiration processing is lower.
Utility model content
The purpose of this utility model is to provide a kind of efficient gas absorption towers, it is intended to the efficiency of exhaust-gas treatment is improved, and
Reduce cost and reduces the corrosion to equipment.
In order to achieve the above object, the base case of the utility model are as follows: a kind of efficient gas absorption tower, including tower body,
Be equipped with exhaust outlet at the top of tower body, tower body lower part side is equipped with air inlet, and tower body lower part is equipped with liquid outlet, the liquid outlet be located at into
Below port, tower body top is equipped with inlet, and the inlet is communicated with water inlet pipe, and the water inlet pipe is located in the middle part of tower body and edge
Vertical direction setting, water inlet pipe are connected with atomising device, and the atomising device is equipped with several, several atomising devices edge respectively
Vertical direction is arranged at intervals on water inlet pipe；Atomising device includes branch pipe and fog-spray nozzle, and the branch pipe is connected to water inlet pipe, branch pipe
Equipped with several, several branch pipes are uniformly distributed along the circumferential direction of water inlet pipe；The fog-spray nozzle is connected to branch pipe；It is connected on water inlet pipe
There is pressure interface.
The working principle of this base case is: the liquid in water inlet pipe enters branch pipe and is sprayed into what is be connected to branch pipe
In head, because being connected with pressure interface on water inlet pipe, the high pressure entered from pressure interface is sent to the liquid in water inlet pipe with height
In the fog-spray nozzle on branch pipe being connected to water inlet pipe, so that liquid be made to spray from the nozzle of fog-spray nozzle.Week of the branch pipe along water inlet pipe
To being uniformly distributed, the circumference range for the liquid covering tower body that the fog-spray nozzle on branch pipe sprays, and multilayer is connected on water inlet pipe
Atomising device, the nozzle in every layer of atomising device can all spray mist, and the gas into tower body can be when moving upwards
Be absorbed in liquid coverage area, the harmful substance in gas and liquid occur chemical reaction and are dissolved in liquid, harmful substance with
Liquid is discharged collection from liquid outlet together.
The beneficial effect of this base case is:
1. realizing that the processing to exhaust gas is absorbed compared to common gases absorption tower pair in this programme by the way of fog-spray nozzle
Used filler when exhaust-gas treatment absorbs, has saved cost, and if liquid load is smaller when use filler to moisten in time
Wet filler will reduce the efficiency to waste gas absorption, and the liquid that fog-spray nozzle sprays directly can be absorbed and be improved with gas contact
Efficiency.
2. spraying device is equipped with multilayer in this programme, gas can be made to contact more to fill with liquid during rising
Point, assimilation effect is more preferable.
3. the branch pipe in this programme is uniformly arranged along the circumferential direction of water inlet pipe, can within the scope of the circle of tower body shape
It is covered at liquid, to increase the contact area with gas, allows gas to enough be absorbed to the greatest extent in liquid range,
Improve assimilation effect.
4. the liquid that this programme fog-spray nozzle sprays can flow downward after being sprayed on tower body along tower wall, then the quilt from liquid outlet
Discharge, reduces liquid in tower body inner wall residence time, and gas is absorbed by the way of filler, and liquid soaks the same of filler
When can touch tower body inner wall and corrosion is generated to tower body, and after to gas treatment, evaporating very on filler
Slowly, tower body is further corroded to also result in, and uses the technical program, liquid can be flowed down from tower body inner wall, be remained
The speed to evaporate in tower body inner wall is also very fast, to reduce the corrosion to tower body.
Further, the fog-spray nozzle quantity at least two being connected on each branch pipe.
The cross-sectional area on usual absorption tower is very big, and the liquid that fog-spray nozzle quantity at least two can be such that fog-spray nozzle sprays exists
The intracorporal area coverage of tower is bigger, contacts with gas more abundant, and gas is avoided just to be discharged not contacting with liquid.
Further, branch pipe is vertically arranged with water inlet pipe, inner sidewall of the one end of the branch pipe far from water inlet pipe close to tower body
It is arranged, the liquid that the fog-spray nozzle on branch pipe is sprayed can cover tower body circle.
One side branch pipe is vertically arranged with water inlet pipe compared to being obliquely installed, be vertically arranged make to fabricate it is simpler,
And it is smaller to take up space when being mounted in tower body；Another aspect branch pipe one end can make on branch pipe close to tower body inner sidewall
The liquid that fog-spray nozzle sprays forms tower body whole circumference range cover to a greater extent, increases the contact area with gas.
Further, the support rod for being used to support water inlet pipe is equipped in the tower body.
Water inlet pipe is provided with liquid, and liquid itself has self weight, if do not supported to water inlet pipe, water inlet pipe is easy
Tower body itself is caused to wear during long-time service, therefore increases that the support of water inlet pipe can be reduced and tower body is worn, together
When can also extend the service life of water inlet pipe itself, and support rod install water inlet pipe when also facilitate operation.
Further, the pressure measuring unit for detecting fluid pressure in water inlet pipe is connected on the water inlet pipe.
Pressure measuring unit, which can be avoided, in this programme damages fog-spray nozzle because the pressure for liquid in pipe generation of intaking is excessive, or
Person avoids because the pressure in water inlet pipe is too small, and influences fog-spray nozzle injection inability, and the fog-like liquid of generation is uneven, to influence
To the assimilation effect of gas.
